curved forni and are seated in the draft openings l5, best illustrate-din Fig. l, with the inner edge of the tube resting on the ledge 17, therear edge of the tube be ing provided with a lug or lip il), which.

engages beneath the floor of the unit l0,

or removing the bed plate units from the lire pot.. lt gives,furthermore, avery rigid closely fitting construction and preferably asat 20, the lower end of the tube 18 will; be flared downwardly to givean increased area and strenghen the construction against the strain onthe lugs or .lips i9,

llhe said tubes i8 at their inner ends are of such formation as to nestwith the other tubes, the end formation of the tubes in the presentinstance being shown as triangular,

since there are four tubes arranged at 90o from one another successivelyabout the burner, but suoli design or formation of the tube ends may, ofcourse, be varied to suit the needs of the particular assemblage oftubes. The inner ends oit the tubes are provided with -vvalls 2l whichabut as shown. in Fig. Ll, so that while the nestedends of the y tubesdeliver a substantially solid olumn of air, the draft currents comingthrough the tubes do not meet and comingle within the tubes or Within acentral ohan'iber, as in sonie constructions now known to me, and theobjectionable orosseurrents and baoldrafts due to any inequalities ofcurrents Corning through the several tubes, are entirely eliminated.This results in a steady and uniform delivery of air from the nested.ends of the draft tubes.

The units lll, as stated, are of segmental forni, in the presentdisclosure, and when assembled provide an open center to reoeive an oilpan 22, the rim Hangs 22 of Wliieh engages over an .upwardly projectingledge 23 extending from the. units l() so as to lool; the unitstogether, The said, pan has at one side, an overflow pipe 24 which willprevent any flooding and overflow of the pan upon starting,- the burner,the said overflow pipe 24k delivering to any suitable receptacle orreservoir. Centrally of the pan 2i? is an open boss having in its top, aseat 26 to receive a perforated plate 27 which is preferably looselymounted in: the seat 2li so that it may be readily' removed and having,as shown, perforations through which air may be fed to the burner or oilhead,

The burner or oil head is preferably of the form shown and comprises aoonoavoconvex disk :2S having on its under .voneavo side a Central boss2l), through n'hieh is a passage 30 which is threaded at its lower endand flares outwardly at its upper unthreaded end into the convex surfaceof the plate or t isla 2S. rlhe oil feed pipe 31 passes loosely throughthe disk 27 andiengages the threads l boss Q9 on the disk 28, the saidfeed pipe 3l; being secured and 'held in position in any suitablemanner. ln order to maintain the oil distributing; disk or head 28 inproper relation to the dra-ft tubes, l preferably provioe a collar orsleeve 3l loosely surroun l- 'ing the oil feed pipe 3l, said collar 3lrestingu at its lower end upon the plate 27 with itslupper end abuttingand sustaining the lower endof the boss 29. These collars or sleeves 314will be of proper length to maintain the oil distributor in its adjustedrelationto the draft tube Vand Will support the plate 28 and the oiltube in position. i

By mounting the plate 27 loosely in the boss 25 with the oil tube 31`traversing it loosely/,and by reason of the manner of assembling thethe other elements as heretofore described, the matter of installing ortaking down the burner is a simple one. The unit construction of bedplate; the separable oil pan with its associated distributor parts; andthe knock-down nested draft tubes provide a burner which can be readilyinstalled in furnaces or heating stoves, through the furnace or stovedoor Without the necessity of taking down or dismantling the furnace orstove proper and forthe` purposes of repair' and replacement, thepresent construetion. is a most convenient one.

ln order that the burner may be fitted to fire pots of varying sizeswithin reasonable limits, and to take care of any slight variations inthe lire pot Wall, I may provide the units l0 wit/h adjustable plates 32eonformingI to the obntour of the units, the plates in the presentinstance, conforming to the segmental sliape of the units. These plates32 will be removably and adjustably secured by means of the slots 33 andthe bolts 34 so that said plates may be extended or retracted Wi thresl'ieot to the circumference of the bed plate and the burner adjustedto varying'v sizes of pots. ln order to prevent any openings or erevieesappearing between the edges of the plates when they are expanded, lpreferably lap the edges of the platos, as shown at 34, so that completeoirouznferential continuity of the' expansible plates is preserved, andno openings whiz-li would iu teri'ere with the up-draft through the lirepot are presented.

The action of the burner when assembled is in general, like the actionof `burners of this type, with this important exreption, namely that the11p-draft from below the grate, which stopped and dirooted by therovering bed plate into and through the curved dratt tubes, is deliveredby these draft tubes under the present construction, in a plurallli cgi
